Recurring themes

Customer Service negative
Many users report extremely poor or non-existent customer support, with slow responses, unhelpful chat bots, and a lack of accountability when issues arise. This is a major pain point, especially when bookings go wrong or refunds are needed. The developer's notes mention 'Have feedback? Reach out to [email protected],' but reviews suggest direct support for issues is severely lacking.R2R17R32R33
Refunds & Cancellations negative
A recurring complaint is Klook's strict no-refund, no-change, and no-cancellation policy, even when errors are made immediately after booking, or when Klook's partners fail to deliver services. Users often lose money due to this inflexibility.R2R14R30R35
Booking Accuracy & Delivery negative
Many users experience issues with bookings not being honored, tickets not working, incorrect dates being selected by the app, or vouchers not being delivered. This leads to missed activities, re-purchases, and disrupted travel plans.R5R9R12R23
Ease of Use positive
On the positive side, many users find the app very easy to navigate, convenient for booking, and appreciate having all their travel details in one place. This is a consistent positive theme, especially for planning trips to Japan and other Asian countries.R1R3R4R6
Pricing & Value mixed
While some users praise Klook for offering cheaper prices and good deals, others report paying double the actual fare or encountering significant markups (10-20% per ticket) compared to booking directly. Some also mention hidden fees or issues with promo codes not applying.R7R12R14R18
eSIM Experience mixed
Many users have a positive experience with Klook's eSIMs, finding them easy to use and reliable. However, a notable minority reports issues with activation, promised data not being available, or service suddenly stopping, particularly at critical times.R1R18R22R26

Who it's for

Klook is for travelers, particularly those visiting Japan and other Asian countries, who want a convenient platform to book activities, transportation, and hotels in one place R1R3R4. It is best suited for those who double-check all booking details carefully and are prepared for potential customer service challenges, as issues are common R153. It is not for users who prioritize reliable customer support, flexible cancellation policies, or guaranteed refunds for booking errors or service failures R2R17R32R153.

Evidence note: The recent reviews skew heavily negative, with a significant focus on customer service failures and refund issues. While many positive reviews praise the app's convenience, the sheer volume and detail of negative experiences regarding support and booking problems suggest these are prevalent issues. The lifetime rating of 4.7 is much higher than implied by recent sentiment, indicating a downward trajectory or that recent users are encountering more problems.

Frequently asked

Based on recent reviews, Klook's customer service is frequently reported as unresponsive, unhelpful, and difficult to reach, with users experiencing long wait times, slow replies, and a lack of resolution for booking issues or complaints R2R17R32R33.
Are Klook's prices always cheaper?
While some users find Klook offers competitive prices and deals, others report paying double the actual fare for tickets or encountering significant markups (10-20% per ticket) compared to booking directly, suggesting prices are not always the cheapest R7R12R14R47.

  6. [R18] 5/5 · US Best Travel App: I have used Klook for a couple of years now and all the services I have picked from pocket sims to esims to tours have been great. Prices are unbeatable. Highly recommended app and must have for travel. 100%
  7. [R20] 5/5 · US Cost and time savings: Klook has all kind of offer and the price sometimes lower than official website like hotel price, easy to book and use the voucher
  8. [R50] 5/5 · US The Best Travel App: The app is simply seamless and easy to use. Often, although not always, activities are cheaper on here than at the ticket counters. I’ve used lots of travel apps, Klook is just unparalleled. Thanks for making my trip to Japan memorable!
  9. [R27] 5/5 · US An Absolute Must !!!: KLOOK makes picking tours so easy! I feel like you could do minimal research for a destination you want to visit and once you arrive just open KLOOK and start booking tours. I LOVE IT !!!
  10. [R26] 5/5 · US Very convenient: Buying an eSIM is very convenient, and if it cannot connect, the refund process is also straightforward. · translated
  11. [R67] 1/5 · US Sudden Service Drop: The 50GB data eSIM we purchased worked well for most of our trip. However, the day of our flight back to the United Stated is a different story. With 6 hours and 13GB left on the Japan Klook eSIM it suddenly stopped working, no service, nada. This was a crucial moment in our trip as we needed to route to the airport and we needed to pull up our boarding passes. The absolute wo
  12. [R2] 1/5 · US DO NOT USE KLOOK - TERRIBLE CUSTOMER SUPPORT WITH ZERO ACCOUNTABILITY: I booked an Alamo rental car at Newark Airport through Klook. When I arrived, the rental counter representative was rude and denied the rental, claiming that I needed international travel documents, even though I am a U.S. resident and did not have or require international travel documents for my trip. I was then told to contact
  13. [R17] 1/5 · US Worst booking platform experience: Order issues are very difficult to resolve. Customer service takes a long time to connect and even longer to reply, maybe once every 3 minutes. The entire conversation takes about an hour, then they say they will follow up via email, but I haven't received any reply in 7 days! · translated
  14. [R32] 1/5 · US Scam Central: Avoid at all costs. Customer service is non-existent. So when they fail to deliver your voucher or other product, they keep you cash and you’re S.O.L.
  15. [R33] 1/5 · US Terrible app no customer support: Terrible app with zero customer support the chat does not work and the email gets no response. There’s no benefit using the app because the companies are not able to to offer support for anything purchased through this app
  16. [R14] 1/5 · US Charged $50 change fee: Just buy train station. This app is rip off. I bought tickets for a week in advance and literally when I pushed the buy button I realized I picked the wrong date. Tried immediately to cancel / change. Charges $50 either way. Rip off scam. Just buy at train station for less money.
  17. [R153] 3/5 · US Beware: No Mistakes: NO CHANGES, CANCELLATIONS, or REFUNDS ONCE PURCHASED! When booking anything on this Klook app, make certain everything is correct and that you’ve explored all options before confirming and paying. While great deals and convenient, there are ZERO changes, cancellations, or refunds for anything. Even if you see cancellation or change policies before confirming payments, afterw
  18. [R30] 3/5 · US non refunds offered: Klook offered up great ideas for excursions for my Japan trip. However-they sold me bullet train ticket at 7pm at night for a 9am train that same day that and i needed a 9pm train-why would you sell a ticket for a train for a time slot that already passed. I asked for a refund because I had to buy 5 more tickets for the right time for same amount and they refused to offer me a
  19. [R5] 1/5 · US Non working tickets: Get train tickets to Kyoto from Tokyo and the QR ticket didn’t work. Asked multiple workers and every gate didn’t scan it and denied us. Miss our train and another worker said to never use third party to buy tickets.
  20. [R9] 1/5 · US Worst app ever!!!: I booked a paragliding activity on this app and received a confirmation email from them. But when I actually showed up, the paragliding operator asked if my booking was made through Klook. They then told me the slots were full and canceled my order on the spot. This completely messed up my entire itinerary. Worst app ever!
  21. [R12] 1/5 · US Charged us double the actual fare: We booked bullet train tickets only to find out we paid double and didn’t even get what was reserved.
  22. [R23] 1/5 · US Terrible APP when booking transfers: Be careful with the app. It will default to a spot your don’t want. Hence if you find out too late like I did you will lose money. I had to rebook a separate transfer. That transfer was even wrong. It picked a hotel pick up to a hotel that didn’t even exist. I had to take a taxi and communicate with the driver to meet at a random corner intersection. Getting a
  23. [R47] 1/5 · US Disgusting travel platform: Twice as expensive as Fliggy. You choose, but I've already deleted it. · translated
  24. [R291] 3/5 · GB These guys are making big Mark-up: Very convenient but the markup is insane. 10-20% per ticket which is unheard of. With a bit of research you can go around that
  25. [R22] 2/5 · US Bonus don't work: Booked teamlabs ticket with this app fine, but it is super ambiguous in terms of whether the discount applies. They also promised a 5 GB E-SIM and send us the QR code, but we follow their instructions and see no option for activating this "gift". The app feels dishonest overall and I would not use again.
  26. [R29] 1/5 · US Get the app first: Make sure you download the app and use that to purchase eSIM. If you use their website it’s impossible to transfer it to your app to actually use it. Support is worthless.
  27. [R43] 1/5 · US Terrible Customer Service and UI/UX: Their app is built incorrectly and selects the wrong day in a booking. For example if you select May 19 and it’s literally highlighted, it saves May 20 instead. Customer service was unwilling to give a full refund, and once we showed them the screenshot of the problem, they gave us a “credit” and still charged us a $50 fee for something that was their fault.
  28. [R82] 1/5 · US Cannot use: Wanna buy Japan esim for 1 Day 500MB Page not loaded
  29. [R98] 3/5 · US Pickup and Fast Track at Ho Chi Minh: Booked Fast Track service at Ho Chi Minh twice with experience of 1- No one was there to meet us as contracted for getting through Immigration 2- 2nd time for pickup had to wait 15+ minutes for car and no offer of help with luggage. The Klook operate airport was rude. Talked sh:t about my impatience but my wife understood Vietnamese.
  30. [R142] 3/5 · US Confusing: Instructions for getting to pick-up or meeting points are vague, inaccurate and confusing.
  31. [R49] 1/5 · US Do not book a tour with these ppl in Florence!!!: When they say be on time, they mean it. They do not make exceptions, no matter how hard you have tried to locate them and how many times you have been misdirected. I watched multiple other people get turned away after only 15 mins late arrival. One lady had been texting their help service way before tour time to never be helped. No number was given
  32. [R101] 1/5 · US esim does not work most of the time: waste my money and time keep trying to get connection don’t buy!
  33. [R310] 3/5 · GB Hotel prices and availability not accurate: It’s a bit frustrating using this app or website as you see a hotel or price and when you click on it it changes completely. Or to a higher price or it’s sold out. Not great when you’re trying organise holidays. So far that’s the only experience I’ve had
  34. [R35] 1/5 · US Do not use for anything immediately time sensitive: Tried to use klook to purchase tickets for a train in Japan since I wasn’t at that station yet and wanted to make sure I got them in case the ticket area was swamped. Despite an hour and a half between purchase and when the train was supposed to depart, I’m sitting here 15 mins after it’s left and the app still says the tickets are processing and
  35. [R25] 5/5 · US Trip to Japan: My trip to Japan is the first time I have ever used Klook to book anything. They make it so easy to book tickets for any show or event. You can even use it to purchase train tickets. I will now use Klook for my future trips.
